Japanese researchers found that lecanemab, an amyloid-clearing drug for Alzheimer’s, does not improve the brain’s waste clearance system in the short term. This implies that nerve damage and impaired clearance occur early and are difficult to reverse. Their findings underscore that tackling amyloid alone may not be enough to restore brain function, urging a broader approach to treatment.
Viagra was developed as a promising heart disease treatment. In trials the side effects we all know of it for came apparent quickly and so they got it approved for that since it is very easy to prove it is helpful. However there is still good reason to believe that it is helpful for a lot of other things and everyone should take it. What isn’t known is if there is anyone who shouldn’t take it, what the best dosage is, and lots of other details - but studies are happening and I expect in 10 years it will be a regular treatment for a lot of people who don’t care about the side effects.
I probably wouldn’t take it, since I have a heart condition and take prescription drugs for it. If other people with my condition like to try first, be my guest, I’d be interested in the results.
Talk to your doctor and read those studies. If you have a heart condition you maybe someone who should start taking it. Or maybe you are amoung those who should never take it. I don’t know your exact situation (and I’m not a doctor), I know just enough that I would not be surprised if viaga would be helpful
